The Big Bang Theory: The Complete Ninth Season continues the saga of Leonard and Sheldon, two genius roommates who are brilliant in the lab, but socially challenged outside of it. In Season Nine, Sheldon embarks on some soul-searching adventures, no doubt entailing substantial revisions to his Relationship Agreement with neurobiologist Amy. Meanwhile, Leonard and Penny tie the knot in Las Vegas ... but how this will affect the Roommate Agreement with Sheldon is anyone's guess.

Meanwhile, Howard and his wife, Bernadette, are living alone in his mother's house (but not for long!), and Raj is not only able to talk with women - but finds the challenges of getting exclusive with only one, Emily (Laura Spencer). With unexpected plot twists, celebrity guest appearances, and moments of social awkwardness that often stimulate an involuntary laugh reflex, The Big Bang Theory: The Complete Ninth Season successfully melds the worlds of sitcom and science into a series that has captured the hearts of fans all over the country, and the world.
